If you go right now, I'd say the aquarium. If you go when all exhibits are open, I'd say Columbus. I've been to both.
I've only been to the Columbus Zoo but we love it! We get a season pass every year! 😊👍
Been to both. Columbus is better but right now two areas are closed until warmer weather comes.
Never been to Cincinnati but Columbus was great fun for family
Never been to Cincinnati but between Pittsburgh and Columbus I'd tell you Columbus
